Question

Can i get help with this problem 

Given the bond dissociation energies below (in kcal/mol), calculate the overall ΔH° for the following reaction:

\[
(\text{CH}_3)_3\text{CH} + \text{Br}_2 \rightarrow (\text{CH}_3)_3\text{CBr} + \text{HBr}
\]

Bond Dissociation Energies:
- (CH₃)₃C–H: 91 kcal/mol
- (CH₃)₃C–Br: 65 kcal/mol
- Br–Br: 46 kcal/mol
- H–Br: 88 kcal/mol
- CH₃–Br: 70 kcal/mol

Options:
- ○ -86
- ○ -16
- ○ 16
- ○ 137
